Python: Interleave multiple lists of different lengths
Interleave Lists of Varying Lengths
Write a Python program to interleave lists of varying lengths.
Visual Presentation:
Sample Solution:
Python Code:
# Define a function called interleave_diff_len_lists that takes four lists as input: 'list1', 'list2', 'list3', and 'list4'.
def interleave_diff_len_lists(list1, list2, list3, list4):
# Create an empty list called 'result' to store the interleaved elements.
result = []
# Get the lengths of the input lists and store them in 'l1', 'l2', 'l3', and 'l4'.
l1 = len(list1)
l2 = len(list2)
l3 = len(list3)
l4 = len(list4)
# Iterate from 0 to the maximum length among the input lists using 'max' function.
for i in range(max(l1, l2, l3, l4)):
# Check if 'i' is less than 'l1' and add the element from 'list1' to 'result'.
if i < l1:
result.append(list1[i])
# Check if 'i' is less than 'l2' and add the element from 'list2' to 'result'.
if i < l2:
result.append(list2[i])
# Check if 'i' is less than 'l3' and add the element from 'list3' to 'result'.
if i < l3:
result.append(list3[i])
# Check if 'i' is less than 'l4' and add the element from 'list4' to 'result'.
if i < l4:
result.append(list4[i])
# Return the 'result' list containing interleaved elements from the input lists.
return result
# Create four lists of different lengths: 'nums1', 'nums2', 'nums3', and 'nums4'.
nums1 = [2, 4, 7, 0, 5, 8]
nums2 = [2, 5, 8]
nums3 = [0, 1]
nums4 = [3, 3, -1, 7]
# Print a message indicating the original lists.
print("\nOriginal lists:")
print(nums1)
print(nums2)
print(nums3)
print(nums4)
# Print a message indicating that the lists are being interleaved, and call the 'interleave_diff_len_lists' function.
print("\nInterleave said lists of different lengths:")
print(interleave_diff_len_lists(nums1, nums2, nums3, nums4))
Sample Output:
Original lists: [2, 4, 7, 0, 5, 8] [2, 5, 8] [0, 1] [3, 3, -1, 7] Interleave said lists of different lengths: [2, 2, 0, 3, 4, 5, 1, 3, 7, 8, -1, 0, 7, 5, 8]
Flowchart:
Python Code Editor:
